Aluminized films mainly include polyester aluminized film (VMPET) and CPP aluminized film (VMCPP). The function of aluminum plating on the surface of the film is to block light and prevent ultraviolet radiation, which not only prolongs the shelf life of the contents, but also improves the brightness of the film. It replaces aluminum foil to a certain extent.
Aluminum foil has very high barrier properties, high temperature resistance, and light protection
PE has thermal bonding properties. Used to bond the above two materials
